That's a great and very practical question! It really depends on the specific design and installation of the trash cans in a given city. Many modern urban bins are indeed designed with mobility in mind. You'll often see models equipped with sturdy wheels, handles, or a lightweight construction, allowing sanitation crews to roll or lift them aside quickly for thorough street sweeping or pressure washing.
For major public events like festivals or parades, cities frequently utilize temporary, highly portable bins. These are often simple, lightweight plastic barrels or specially designed units that can be easily placed along routes and just as easily removed afterward. They prioritize function and flexibility over permanent, heavy-duty construction.
However, not all city bins are meant to be moved. Some heavier, anti-vandalism models or those that are bolted or concreted into place are intended as permanent fixtures. Their primary goal is security and durability, not mobility. For routine cleaning around these, workers typically clean *around* them or use specialized equipment.
So, the short answer is: yes, many can be, and for planned events, cities use bins that are specifically chosen for easy movement. It's all part of modern, efficient public space and waste management. The key is having the right type of bin for the right situation.
